KEEY Aerogel proposes the creation of new value chains by expanding the size and attractiveness of silica-based waste sources by their transformation to highly added-value aerogel material: a nanoporous material with the best thermal insulation performance in ambient conditions. Compared with available materials, only the 15% of the thickness is required for the same thermal insulation factor. This product “SIlica Closed Loop Aerogel” - SICLA is made to significantly contribute to achieve the reduction of both energy consumption and CO2 emission. It can moreover achieve higher resource efficiency thanks to a significantly high share of C&DW recycled secondary raw materials in the final product (more than 75% of the total product weight). This technology is made available for strategic companies in the insulation market.
